VOLTAGE THRESHOLD SAFEGUARD: Over-Discharge Protection: This battery management module provides a wide range of adjustability for discharging modes and parameter configurations. Users can define parameters to automatically disconnect the battery upon reaching a preset voltage threshold, effectively preventing over-discharge and prolonging battery lifespan (Important: The relay lacks an integrated power cutoff mechanism. Always manually cut off the power supply post-disconnection; failure to do so will drain the battery to 0V). Its customizable parameters allow precise adaptation of the power management system to rare operational needs and user preferencesSIMPLIFIED FUNCTIONALITY: To reset to factory defaults, turn off the device, press and hold both buttons together, then power it back on. The display will show “888” to confirm factory settings restoration. By default, the protection voltage is preset to 12V, paired with a 2V differential value, which defines the voltage gap required to disconnect and later reconnect the battery. In case of sudden power interruption, the system retains user-configured settings, safeguarding critical data and enabling uninterrupted workflow continuity upon rebootFUNCTIONAL COVERAGE: This module operates as a voltage controller utilizing a relay-based mechanism to switch output power on/off. The relay serves exclusively as a switching component, maintaining the original voltage level without modification. Designed as a protective switching module, it does not integrate batteries. It is compatible with lead-acid batteries, lithium-ion batteries, and solar panel batteries (single units only)PARAMETERS: Board Size:Board Dimensions: 57×42×19 mm (2.24×1.65×0.75 in, L×W×H); Input Voltage Range: DC 12–36V; Voltage Measurement Precision: ±0.1V; Energy Consumption: Perfect for everyday use. top-grade materials and excellent craftsmanship ensure long-lasting durability.
